Managing Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants Concomitant use with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, is a risk factor for respiratory depression and death [see Warnings and Precautions ( 5.2 )].

Reserve concomitant prescribing of benzodiazepines or other CNS depressants in patients in methadone treatment to those for whom alternatives to benzodiazepines or other CNS depressants are inadequate.

Concomitant use with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, and death.

…with Methadone Concomitant use of methadone and benzodiazepines and/or other CNS depressants (e.g., alcohol, non-benzodiazepine sedative/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids [gabapentin or pregabalin], and other opioids), increases the risk of adverse reactions including overdose and death.

In others, gradually tapering a patient off a prescribed benzodiazepine or other CNS depressant or decreasing to the lowest effective dose may be appropriate.

Carefully monitor cardiac rhythm when administering SUPRANE to susceptible patients (e.g., patients with congenital Long QT Syndrome or patients taking drugs that can prolong the QT interval).

Benzodiazepines and Opioids (MAC Reduction) Benzodiazepines and opioids decrease the amount of desflurane (MAC) needed to produce anesthesia.

Neuromuscular Blocking Agents Anesthetic concentrations of desflurane at equilibrium (administered for 15 or more minutes before testing) reduced the ED 95 of succinylcholine by approximately 30% and that of atracurium and pancuronium by approximately 50% compared to N 2 O/opioid anesthesia (see Table 4).

During maintenance of anesthesia, the dose of nondepolarizing muscle relaxants is likely to be reduced compared to that during N2O/opioid anesthesia.

• Concomitant use of N 2 O, benzodiazepines and/or opioids reduces the MAC of SUPRANE.
